Explorer.exe (ieframe.dll) Error

I keep getting the following error when I am in the middle of typing an address in the Run command (start menu>run): "Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience." The error signature is: AppName: explorer.exe AppVer: 6.0.2900.2180 ModName: ieframe.dll ModVer: 7.0.6000.16441 Offset: 000c83b3
I think this error started to occur after installing a windows update. I have Windows XP Pro SP2 with IE 7 installed. Please let me know if anyone knows the solution. Thank you.

I don't have any problem with right clicking on HD and choosing Explore. It only happens by starting to type in the Run, and when Windows is about to bring suggested addresses (or the recent typed addresses). I realized today that this begins to happen after starting Windows Internet Explorer 7, meaning if I don't use IE 7 it doesn't happen. I don't think this would be a IE7 bug since I know many people who use it without having any problem. Thanks for your suggestions. I hope I get the solution soon
